Miniature rose plant named `Briincog`

ABSTRACT

A new and distinct variety of miniature rose plant characterized by a profusion of exhibition form blooms that are an unusual combination of colors, consisting of mauve and yellow with a light fragrance, held on relatively long, strong stems.

FIELD OF THE INVENTION

The present invention relates to a new and distinct variety of miniature rose plant which has been given the international variety recognition designation, `Briincog`, and is to be marketed in this country under the synonym `Incognito`.

PLANTS RELATED TO THE INVENTION

The plant of this invention was originated as a result of a planned breeding program and controlled crossing which had as the seed parent the cultivar, `Jean Kenneally` (U.S. Plant Pat. No. 5,637) and as the pollen parent, `Twilight Trail` (U.S. Plant Pat. No. 6,198). The plant of the invention was a selection from the progeny of the stated cross, and has been asexually reproduced by the taking and rooting of stem cuttings. Such asexual reproduction as performed at Lawndale, N.C., has shown conclusively that the characteristic and distinctive features of the plant come true to form and are faithfully transmitted through succeeding propagations, thus establishing that `Briincog` is stable.

`Briincog` is readily distinguished from its parents by the unusual color combination of lavender with yellow on the reverse of the petals, its stronger growth habit, and by its petal substance.

SUMMARY OF THE INVENTION

Among the new and novel characteristics which are possessed by this plant, which distinguish it from its parents and from all other miniature rose cultivars of which I am aware are:

1. Blooms of unusual mauve and yellow blend coloration that are well formed , blemish resistant, and show exceptional form and substance;

2. Abundant blooms which are borne singly, and in clusters of up to 7 blooms, on strong stems of from 4 to 7 inches in length;

3. A light fragrance;

4. An abundance of glossy, medium to dark green foliage which pleasingly contrasts with and highlights the blooms; and

5. Higher than usual disease resistance to common rose diseases with a higher than usual level of vigor, and growing to a height which is typical of roses of this market class to produce a plant which attractively appoints the home garden while providing cut flowers of exhibition form and quality.

BRIEF DESCRIPTION OF THE DRAWING

The single sheet of the accompanying drawing is a photographic illustration which shows foliage and typical specimens of the flowers of the new variety in different stages of development. Colors illustrated are as accurate and true as is reasonably possible to attain in color illustrations of this type. In this regard, it should be noted that the apparent yellow coloration in the upper surface of the petals is not a characteristic feature of the plant and may be due to reflectance. The petal coloration designations of the petal undersurface changes from the time the bloom begins to open, depending upon the temperature and weather conditions (for example, the warmer the weather, the deeper the yellow hues).

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of my new variety of miniature rose, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.), except where common dictionary terms of color definition are employed.

Type: Hardy dwarf, bushy, compact, seedling greenhouse, outdoors, cut flower, garden decoration, potted plant.

Commercial class: Miniature.
